The primary structure of histone H2B from brown trout (Salmo trutta) testes.

چکیده
Histones are basic proteins associated with the DNA of eukaryotic cells, and appear to have a fundamental role in the organisation of the chromosomes of higher organisms [l-3] . Comparative primary sequence information is available for most of the major histones (for recent review see [3]). However the complete primary structure of histone H2B is known only for calf thymus [4] . Here we present the primary sequence of histone H2B isolated from brown trout (Sulmo truttu) testes. Comparison of the primary structure of histone H2B between trout testes and calf thymus indicates that the trout histone H2B differs by deletion of two residues, and substitution of seven other residues. All observed changes except one have occurred in the N-terminal half of histone H2B.

The length-weight relationship, age, growth parameters, sex ratio, mortality and exploitation rate of Salmo trutta fario were determined in Lar dam. The sex ratio (male: female) was 1:1.84 which differed significantly from the expected 1:1. The length-weight regression was (females) and (males) indicating a negative allometric growth for both sexes. Growth parameters were estimated as L∞ = ...

متن کاملFeeding behavior of brown trout, Salmo trutta fario, during spawning season in four rivers of Lar National Park, Iran
Brown trout, Salmo trutta fario, has a wide range of distribution in the north of Iran and in Karaj, Lighvanchai and Karun Rivers, but there is no report about its feeding behavior in some water resources including the Lar Natural Park. In order to study feeding behavior of this fish during spawning season, a survey was carried out in the rivers of Elarm, Aab-Sefid, Kamardasht and Delichayi in ...
